Who responds to customer issues on Fridays?
Not a comment out of the side of my mouth, I am legit curious. at any rate, an occasional 5 day week is better than an occasional 6 day week
We don't _yet_ do support on-call on the weekends.
As long as they're up front with us when hiring it seems fine to me. If you don't want to be on call, that's something you need to factor into your job search. I've always factored it in for my searches!
